A switch assembly including a switch and a controller connected to the switch to control the switch. A conformal spacer may be formed upon a portion of a flare length proximate a tip of the write pole. The power converter also includes first and second active phase legs including a main switch series-coupled with an input node of the power converter and the first section of the tapped windings of the first and second tapped inductors, respectively. Preferably, the anchoring device is a novel, toggling type in which a toggling member is pivotally attached to the flexible member at a ball joint.
